In early 2013 a Latin manuscript was discovered that contains some fascinating early medieval recipes. The manuscript dates from 1140 from the Durham Cathedral monastery in the UK. The recipes are primarily medicinal in their variety, with the intent to heal the sick and infirm. These recipes are nearly 150 years older than other known medieval era recipes.
I wish I could find a bit more information but it doesn't seem that any individual recipe translations have yet been published. The researchers are apparently working on a book that will be titled "Zinzibar" which is the Latin word for ginger.
